Classification in Wisconsin: Prohibited
Species Assessment Groups (SAG) were assembled to recommend a legal classification for each species considered for NR 40. The recommendation for porcelain berry was based upon this literature review developed by the department.
Leaves: Shapes vary from heart to palmately lobed with tendrils opposite of the dark green leaves. Leaves dissected. Hairs present on the leaf veins.
Flowers: Small green-white flowers bloom in clusters during mid-summer.
Fruits & seeds: Shiny, clustered berries occur in fall and are a range of colors from pink to purple to blue with small white and gray spots; the flesh is white.
Roots: Fibrous and can resprout from root fragmentation.
Similar species: Native grapes (Vitis spp.) are also woody vines but with shredding bark when mature. Leaves are sometimes hairy, but generally on the surface of the leaf and sometimes on the veins. Stem pith is brown compared to porcelain berry’s white pith and the fruit of native grapes are green, black, or purple and watery.
Refer to the ID guide for porcelain berry, provided by Frank Hassler of Good Oak Ecological Services, for assistance with the identification of porcelain berry during the winter.
Mechanical: Vines can be pulled from trees and cut or mowed to prevent flowering. This will not eradicate but will control. Small plants can be hand-pulled before fruit.
Chemical: Cut stump with glyphosate; basal bark in fall with triclopyr and surfactant.
